Weight, Mass And Gravity

Question 1

Gravity attracts all masses. True or false?

Answer 1

True, only noticeable if one is big eg planet

Question 2

What 2 effects does gravity cause?

Answer 2

1) everything on a planet falls towards the ground

2) gives everything a weight

Question 3

Difference between weight and mass?

Answer 3

Weight: force acting on object due to gravity, depends on the strength of gravitational field at the location of the object, measured in Newton’s using s calibrated spring balance
Mass: the amount of ‘stuff’, has same same value anywhere, not a force, measured in kg with a mass balance

Question 4

Weight and mass are…

Answer 4

Directly proportional

Weight (N) = mass x gfs (N/kg)
